APPARATUS FOR-"CONTROLLING TRAINS on RAILWAYS.

Specification of Letters Patent. Patented Dec. 21, 1915.

Application filed July 14, 1915. Serial No. 39,787.

Be it known that I, JOHN WfLLIAM IVRIGHT, a subject of the King of Great :Britain and Ireland, residingat 134: Manchester street, Oldham, in the county of Lancaster, England, have invented new and useful Improvements in or Relating to Apparatus for Controlling Tra ns on Bailways, of which the following is a specifica- 'tion.

' This invention relates to apparatus for controlling trains on railways and has special reference to apparatus of the kind wherein a ramp arranged at the side of the track in conjunction with a signal and raised and lowered intoand out 'o'f'operative position simultaneously w i th or independently of the raising and lowering of the Slg: nal, is adapted, in the event of over-running of'the signal, to be engaged by a vertically movable rod mounted on the engine, which rod is thereby actuated and cuts off the steam and also operates the brake valve to.

apply the brakes.

The present invention comprises improved apparatus of the kind referred to..

According to my invention I employ'a ramp having a long and a shorter ramp parts or surfaces adapted in operation to be engaged by two vertically movable rods mounted on the engine and I so arrange said surfaces and rods that the rod which reference to the accompanying drawing wherein Figure 1 is an elevation and Fig. 2 a plan illustrating my improved apparatus in the lowered or inoperative position. Fig. 3 is an end view of Fig. 1 and Fig. 4 is an elevation showing the apparatus in the raised or operative position. 7

Referring to the drawing, a is a ramp having two ramp parts or surfaces 6 and b one of which, 5, is considerably shorter than, and projects at its lower or front end beyond, the other 6 The ramp at is supported by arms c pivoted to it and to brackets cl mountedon the sleepers or otherwise suitably disposed at the side of the track. -The ramp is adapted to be raised and lowered in conjunction with or independently of the signal by suitable operatmg means which may be duplicated in order thatthe ramp may be actuated from either the signal cabin in front of or the cabin beyond it. Conveniently the operating means may comprise lifting levers e, 6 links 7', f rods h, h bell-crank levers j, j links is, k and hand levers m, m The link 7 is directly connected to the lifting lever e and the link f operates the lifting lever 6 the engine and provided at their lower ends with anti-friction rollers. The rod 0 which co-acts with the shorter part or surface 5 is connected to the slotted arm of a bellcrank lever q the other arm of which has pivoted to it one end of a link r. The other end of the link r is curved and slotted to co-act with a pin 8 on the steam regulator lever 25. The upper end of the rod 79 which co-acts with the longer ramp part or surface 6 and is arranged behind the rod 0, is pivoted to the slotted arm of a lever u the other arm of Which is pivoted to one end of a link o curved at its other end which is slotted to co-act with the handle of the brake valve lever w.

In operation the rods 0 and p co-act with the ramp parts or surfaces 5 and 6 whereby they are actuated, and, through the levers q and'u and links r and o, operate the regulator lever t and the brake valve lever w to cut off the steam and apply the brakes. Owing to the arrangement of the ramp parts or surfaces 6 and Z2 and the rods 0 and p, the rod 0 co-acts with and is actuated by the part or surface 6 before the rod 3? co-acts with and is operated by the part or surface 6 By this means the steam regulator lever 25 is fully operated and the steam completely out ofi at once but the brake valve handle to is gradually operated and the brakes are gradually applied and are not fully applied until the roller on the rod 29 has traversed the full length of the ramp part or surface b The slotted ends of the links r and 1) allow of the independent operation of the steam regulator lever and the brake valve lever. By only partially raising the ramp a it can be set to partially cut off steam and apply the brakes and so reduce the speed of an engine or train without bringing sa me to a standstill.

WVhat I claim as my invention and desire I projecting at its lower or front end beyond to secure by Letters Patent is 1. In apparatus for controlling trains on railways, the combination of a ramp adapted I to'be raised and lowered in conjunction and simultaneously with the signal; a short ramp surface on said ramp; a long ramp surface on said ramp; a movable rodinounted on the engine .v adapted to co-act with said short ramp surface, when raised, and to be at once fully operated thereby; means connecting said rod with the steam regulator; a second movable rod mounted on the engine adapted to co-act, with said long ramp surface and to be gradually operated thereby; and means connecting said second 'rod with the brake valve.

2. In apparatus for controlling, trains on railways, the combination of a ramp ,ad'apt ed to be raised and lowered in conjunction and simultaneously with the signal; a long ramppart on said ramp; a movablefrod mountedon the engine adapted to-co-act Copies of this patent mey be obtained for ving beyond end. i I a I V In testimony whereof I have signed my with and be gradually operated by said ramp part; n1eans connecting said 'rod with the brake valve; a short ramp part on said ramp said long ramp part a second movable rod mounted on the engine adapted to co-act with and be fully operated by said short ramp part before the first rod is operated by said long ramp part; and means connecting said second rod with the steam regulator.

3. In a ramp forcontrolling' trains on railways and adapted to be raised and loweredlin conjunction and simultaneously with the signal, the combination ofwa long ramp part and .a short ramp surface arranged alongside saidlong ramp part andprojectthe same at its lower or front name to this specification in thev presence of two subscrib ng witnesses.
